We have one of those signs at Greenwood and Highland and believe me, it doesn't do much good. Unfortunately, the police do not always have time to park and watch, they are too busy chasing drug dealers, trying to "corral" the school kids who insist on fighting after school or terrorizing the school bus drivers, or following up on houses that are robbed or vandalism to cars and property - that's what its all about in case you weren't sure.
